I built my first web server literally from scratch (standard socket lib) today! In Python <3.
It is able to execute php and get the stdout to use it in the Python script afterwards and make use of parallel connections.

Now to the real rant...
I am using HTTP/1.1. I want to use h2 (aka HTTP/2) tho. I am stuck on this. Found the papers to the specs of the h2 and spdy protocols, but they are not really helpful.

Is anyone good in this field? Please let me know :/
